512 DEBUG5 is defined, print out each fixup before and after
514 (fixup_segment): If DEBUG5 is defined, print out each fixup before
515 and after processing.
516 (print_fixup): Added prototype. Show address on first line. Show
517 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if

525 * Makefile.in (all): Depend on .gdbinit.
526 (.gdbinit): Rebuild from gdbinit.in by running config.status.
528 * gdbinit.in: Define new function "pf". Fix doc on "pe" and "ps".
530 * write.c (print_fixup): Print source location on first line.

545 processing if add_symbol is undefined or in expr_section.
546 (resolve_symbol_value, case O_add): For symbol plus
547 constant-valued symbol, convert to O_symbol and re-reduce.
548 (S_GET_VALUE): If symbol needs resolving, resolve it.
549 (indent_level): No longer static.
550 (print_symbol_value_1): Don't print frag address if it matches
551 zero_address_frag. Don't print "resolving" if already resolved.
552 Print segment name. Don't call print_expr_1 on an undefined
554 (print_expr_1): Fix whitespace before printing X_add_number.
556 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
557 not symbol_new, for symbols holding expression values.
558 * expr.h (make_expr_symbol): Move declaration here.
559 * write.c (fix_new_exp): Handle O_add by creating an
560 expression-valued symbol, and calling fix_new_exp recursively.
561 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
562 undefined symbol and a constant, fold the constant into the fixup,
563 and refer to the undefined symbol directly. Then process the
564 fixup again from scratch.
565 (write_object_file): Before calling adjust_reloc_syms, make a pass
566 through the symbol list trying to resolve values.
568 * write.c (print_fixup): New routine, for debugging.
569 (write_relocs): Call bfd_install_relocation. Deleted various
570 hacks for working around problems with bfd_perform_relocation.

578 * config/tc-mips.c: Include subsegs.h.
579 (md_apply_fix): If an unconditional b or bal overflows, and we are
580 not assembling PIC code, replace it with a j or jal.
582 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
583 Use as_bad_where and as_warn_where rather than as_bad and as_warn.

587 * write.c (write_relocs): Add file name and line number to
588 as_fatal calls. Handle bfd_reloc_overflow case specifically when
589 RELOC_EXPANSION_POSSIBLE.
591 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
593 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
594 here. Use them for deciding which PRINTF*LIKE macro definitions
596 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
597 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
598 default definitions matching what we were doing before.
599 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
600 always use the varargs form if not using stdarg. It's safe to
601 always use vfprintf, because libiberty will provide it if the
602 native system doesn't. Also, always make format be const.
603 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
605 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

618 (listing_newline): Check filename as well as line number when
619 deciding whether to record it.
620 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
621 false (if defined) as well as checking for reg_section.
622 (listing_listing): Iterate fetching lines while line number is too
623 low, and we haven't run off the end of the input file.
625 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
627 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

639 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
640 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
641 zero. Don't call obj_frob_forward_symbol.

651 md_create_short_jump, md_create_long_jump.
652 (brtab_emit): Use data_section, not SEG_DATA.
654 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
656 * config/vms-conf.h: new file, manually derived from conf.in.
657 * config-gas.com: use it, and eliminate obsolete "host.h".

667 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
668 from the csect of the enclosing block.
670 * config/tc-mips.c (insns_since_cache_access): Remove.
671 (append_insn): Remove setting of insns_since_cache_access, and

674 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
676 * config/tc-mips.c (md_shortopts): Remove E.
677 (md_longopts): Add EB and EL.
678 (md_parse_option): Handle -EB and -EL as separate options, rather
679 than as a single -E option with an argument.
681 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
683 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
684 involving global symbols too.
686 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
688 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
690 * configure.in: Test for remove, not delete. Fix cross-assembler

702 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
703 many others): new macros; values obtained from "DSTRECRDS.SDL".
704 * config/obj-vms.h (various): use them.
705 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
706 representation (only enum bitfields can avoid being bitstrings).
707 (bitfield_suffix, setup_basic_type): new routines.
708 (VMS_typedef_parse): use them. Now recognize bitfields of all
709 integral types, not just type `int'. Caveat: the representation
710 used for bitfields still does not work for objects placed in
711 registers, and gcc's optimizer sometimes puts small structs there.
713 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
715 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
717 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
718 (tc_frob_label): define this to call vms_check_for_special_label,
719 and declare the latter.
720 * config/obj-vms.c (vax_g_doubles): declare this file-scope
722 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
723 (vms_check_for_special_label): new routine (tc_frob_label).
724 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
725 and `gcc2_compiled.' labels; they won't reach here any more.
726 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
727 double', use `vax_g_doubles' flag to select type of double.
728 (VMS_write_object_file) [traceback setup]: don't pass symbols
729 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
730 and TBT_Routine_End functions.
732 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
734 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
735 S_GET_VALUE() to avoid many repeated function calls.
736 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
737 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
738 gets requested. [All the HACK_DEC_C_STARTUP code appears to
739 be obsolete; gcc does it automatically for vms target. It's
740 also misnamed, because it is for the "VAX C" run-time library,
741 not the newer "DEC C" one which has much different startup code.]
742 {various}: use `S_SET_xxx(symbol,new_value)' rather than
743 `S_GET_xxx(symbol) = new_value'.

747 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,

752 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
754 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
756 * expr.c (expr): Don't reduce the difference of two symbols in the
757 same frag if the symbols are not in normal sections.
759 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
760 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
761 (obj_attach_unwind_info): Do not define. Not needed anymore.
762 * config/tc-hppa.c: Delete whitespace at EOL.
763 (struct hppa_fix_struct): Delete fx_unwind field and all references.
764 (fix_new_hppa): Last arg is now a pointer to an int. Do not
765 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
766 fixups, store 32bits of unwind information in the fx_addnumber
768 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
769 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
770 pointer to 32 bits of unwind info.
771 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
772 pointer to the dummy symbol; set the addend field to fx_addnumber.
773 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
774 rather than &bfd_XXX_section.
776 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
778 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
779 value by one; discard adjustments previously being made. From
782 VMS- and Vax-related changes from Pat Rankin:
783 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
784 * vmsconf.sh: no longer have make-gas.com echo text about needing
785 to modify the gcc-vms driver when intending to use with gcc 1.x.
786 * as.c (parse_options): suppress 'v' from std_short_options and
787 eliminate VMS-specific conditional initialization;
788 [default case]: check for '-v' if md_parse_options doesn't recognize
790 [default case, #if VMS]: check for filename argument when '-v' seen;
792 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
793 for O_big literal operands (double floats and long long ints);
794 [VMS, md_shortopts]: add second colon after 'v';
795 (md_parse_options) [VMS, case 'v']: check for argument, so
796 caller can handle `-v' w/o arg.

847 Update for autoconf 1.118:
848 * gdbinit.in: New file, created from old .gdbinit.
850 * aclocal.m4 (GAS_GDBINIT): Deleted.
851 * configure.in: Don't use it. Instead, generate .gdbinit from
852 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
853 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
854 to ensure that older versions of autoconf aren't used.

1920 VMS debugger now recognizes `long long' variables correctly.
1921 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
1922 for gcc2's predefined types "long double" (same as double, as
1923 per gcc's current state), "long long int", "long long unsigned
1924 int", and final `otherwise' case (to avoid uninitialized type
1925 and size fields). [caveat: predefined types "complex int",
1926 "complex float", "complex double", and "complex long double" are
1929 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
1930 of 0, because the latter indicates success rather than failure

2294 source files from other directories into objects in the current
2295 directory, and specify PSECT attributes explicitly to linker.
2296 Also added missing label.

2385 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
2386 don't spew remainder of input file in error message.
2387 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2388 message with reloc type and try to process remainder of file.
2390 * doc/Makefile.in (install-info-as, install-info-gasp): New
2391 targets, now explicitly checking $(srcdir) for info files.
2392 (install-info): Depend on both of them; do nothing more.

2400 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2401 flag rather than signedp field. Only permit extended range if
2402 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2403 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2405 * config/tc-ppc.c (ppc_size): New static variable.
2406 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2407 (md_begin): If an instruction has a size specific flag set, only
2408 add it if we are assembling that size.
2410 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2412 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2413 cross section PC relative relocs right for COFF and ELF.
2415 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

2428 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2429 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2430 and -many (all architectures).

2441 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2443 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2444 branch with an instruction that uses $at, in case the branch is
2446 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2447 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2448 to make it pcrel_offset.
2449 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2450 reloc->address; another gruesome hack to get gas reloc handling to
2453 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2455 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2458 (emit_insn): New function.
2459 (md_assemble): Call it.
2460 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2462 (lituse_pending): New variable. Set by anything that generates a
2463 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2464 tested by code that might want to emit a LITUSE reloc.
2465 (emit_unaligned_io): New function. Currently calls md_assemble,
2466 but it should eventually be converted to generate the insn itself
2467 and call emit_insn directly.
2468 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2469 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2470 emit_bis_r): Likewise.

2477 the value can't be resolved.
2479 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2481 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2482 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2483 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2485 (mips_force_relocation): New function.
2486 (md_apply_fix): Set fixP->fx_done appropriately.
2487 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

2495 * config/tc-mips.c (enum mips_pic_level): New enum.
2496 (mips_pic): Change from int to enum mips_pic_level. Change all
2497 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2498 (load_address): Handle EMBEDDED_PIC.
2499 (macro): Handle EMBEDDED_PIC in all PIC cases.
2500 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2501 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2502 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2503 works). Do not permit -G with SVR4_PIC.
2504 (s_abicalls): Warn if -G was used, and force -G 0.
2505 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2506 anything but a.out, not just for ELF. For ECOFF, don't generate a
2507 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2509 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2511 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2513 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2514 parameters to avoid losing when compiling with HP CC.
2515 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2517 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2519 * Makefile.in (config-stamp): If `defs' is defined, emit a
2520 preprocessor directive to create a macro named by this value into
2521 config.new; don't explicitly go for BFD_ASSEMBLER.
2522 * configure.in: Define `defs', not `BFDDEF'. Set it to
2523 MANY_SEGMENTS for any obj-coffbfd target.
2524 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2525 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2527 (LOCAL_LOADLIBES): Deleted.
2528 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2529 * config/m88kcoff.mt (TDEFINES): Ditto.
2530 * config/ebmon29k.mt: Deleted.

2533 * config/sparc.mt: Deleted.
2534 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

2555 bfd_set_symtab is called.
2556 (dump_section_relocs): Note whether a symbol is a section symbol
2558 (adjust_reloc_syms): For now, always supply an absolute symbol for
2559 fixups without symbols but not yet `done'. Use section_symbol to
2560 get the symbol, instead of going directly for abs_symbol.
2561 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2562 reloc is not a section symbol and is not in the symbol table.
2563 (set_symtab): New function, broken out from write_object_file.
2564 Counts symbol table instead of relying on an earlier count.
2565 (write_object_file): Call set_symtab, but do it after potentially
2566 invoking the *_frob_file macros. Don't bother counting symbols.
2567 Call symbol_remove, instead of expanding it in place. Moved the
2568 conditionalized `object_file_size' declaration down to
2569 conditionalized block where it's used. When using the absolute
2570 symbol for a fixup without a symbol, set sy_used_in_reloc.
2571 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2572 the correct symbol for the absolute section.
2574 * subsegs.c (section_symbol): Use symbol_new instead of
2575 symbol_make, since we may want it to go into the symbol table.
2576 Make the new symbol have internal linkage. If
2577 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2578 symbol with the newly created GAS symbol.
2579 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2580 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2585 (in_signed_range): New function.
2587 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2588 (sparc_ip, label "immediate"): Reject constants for pcrel
2589 instructions only if the relocation type indicates a "call"
2590 instruction and the offset is within range of a "jmpl %g0". If
2591 it's not in range, use the absolute section symbol plus an offset.
2592 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2594 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2596 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2599 * configure.in: Eliminated all targets using obj-coff but not
2600 defining BFD_ASSEMBLER; I think all such targets that are
2601 supported will be matched by real CPU-OS combinations earlier in
2603 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2604 some comments about the dpx2 configuration, but left it disabled,
2605 since it couldn't be reached before.
2606 (target a29k-amd-ebmonold): Deleted.
2608 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2616 the 'j' operand if there are no further alternatives for this
2619 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2620 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2621 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2623 * config/tc-mips.c (mips_align): Take new argument, label, and use
2624 it instead of global insn_label.
2625 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2626 call to mips_emit_delay and pass it to mips_align.
2628 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2630 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2632 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2633 argument to a .callinfo directive. Don't loop forever on errors.
2635 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2636 use pre-defined registers as arguments.

2640 * write.c (write_object_file): Check both S_IS_LOCAL and
2641 S_IS_EXTERNAL when deciding whether to discard a symbol.
2643 * config-gas.com: Scan Makefile.in, not version.c, for current
2644 version number. Delete all versions of temp files when finished
2645 with them. Create config.h.
2647 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2648 values to reduce number of lookups with S_GET_VALUE. Skip debug
2649 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2650 holger@botbso.rhein-main.de.)
2651 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2652 field. (Also from Holger Teutsch.) Watch for a would-be register
2653 mask that spans frags.
2655 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2656 this_base, not line_base. (Patch from Andreas Arens,
2657 ari@obelix.av.rwth-aachen.de.)
2659 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2660 look local if they're exported or undefined. Used to be done for
2663 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2664 Get it from the looked-up symbol, instead of using the string from
2665 the input stream, which is no longer null-terminated.
2666 (LEX_PCT): New macro, defaults to 0.
2667 (lex_type): Use it for `%'.
2669 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2670 (vip_op): Now static, and returns void. Callers changed. Added
2672 (vip): Ditto. Call as_fatal directly if a program bug is

2719 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2720 0xffff for 'j' to be compatible with MIPS assembler. These

2737 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

2806 BFD_ASSEMBLER is defined.
2807 (mem_fmt): Since COFF doesn't handle callx relocations yet, treat

2810 (tc_bout_fix_to_chars): Store symbol index for all callx
2811 relocations, regardless of link-relax setting.

4794 default is to assume production environment, and reject configs
4795 still being worked on. Mark Elf configurations (except sparc and
4796 i386) as developmental. Deleted cases matching some generic names
4797 in favor of more specific names. (E.g., when we get Alpha

4825 Add comments to functions. Delete unused functions, variables,
4826 #defines, etc. Delete unused members within structures. Delete
4827 ldil;ble hacks -- it is believed they were installed to work
4828 around old gas bugs. Avoid using mixed case for local
4829 functions, variables, and structures. Fix formatting problems
4830 not found by GNU-indent. Add FIXME notices for things which
4831 should be worked on the near future. Delete lots of old
4832 useless (1.36 PA-SOM) code.

4911 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4913 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4914 ELF, since the ELF object format does not have these type of
4915 relocations. Change the abort into as as_bad and return
4916 BFD_RELOC_NONE to silence compiler warnings.
4917 (md_assemble): Keep track of the instruction size. Allow white
4918 space between the $ and the constant for compatibility with older

7324 source directory, if that's not the current directory.
7326 * configure.in (per-host): Accept MIPS host with BSD version

7363 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

7370 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
7372 * Makefile.in: add dvi target; as-$(config).texinfo might live in

7403 dropping a space immediately following an identifier.

7405 lines; I don't think that can be done portably.
7406 * config/tc-mips.c (macro): Use $AT if target register is zero in
7407 load instruction, which it can be for a floating point load.

7430 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)

7531 * make-gas.com: Find obstack.obj if it's not in the current
7533 * read.c (s_ignore): Don't declare is_end_of_line. It's
7534 redundant, and triggers a VMS gcc compiler bug.

7596 (zero_address_frag, bss_address_frag): Now initialized at run
7598 * as.c (main): Call frag_init.

7869 (operand): Treat zero byte as end-of-operand.
7871 * configure.in (per-target): Look for with_bfd_assembler option.
7872 For now, only accept "no", until the merge is done.
7874 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):

7885 (which will be declared in obj-vms.h).
7886 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7887 Fix arguments to VMS_write_object_file.
7888 * config-gas.com: New file. Script for VMS systems to set up the

7958 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7959 declare with format attribute for -Wformat checking.
7961 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7963 * app.c, config/tc-*.c: Don't include read.h, since it is already
7966 * These are based on patches from Minh Tran-le
7967 <mtranle@paris.intellicorp.com>.
7968 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7969 obj_format coffbfd and gas_target i386coff for target.
7970 (i[34]86-*-isc*): New host (uses sysv).
7971 * config/i386aix.mt: Removed (no longer used).
7972 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7974 (LDFLAGS): Added, defined as -shlib.
7975 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7976 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7977 (DOT_LABEL_PREFIX): Define.
7978 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7979 name rather than L0\001.
7980 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7982 * symbols.c, symbols.h (local_bss_counter): Removed.
7983 * write.c (write_object_file): bss no longer uses
7984 local_bss_counter. Pass correct data and bss size to
7985 VMS_write_object_file.

7991 (size_section): Restored sanity check.
7992 (do_relocs_for): Base section address on s_paddr rather than
7993 computing it. Adjust a29k R_IHIHALF special case to account for
7994 section paddr (used to require paddr to be zero). If there are no
7995 reclos, set s_relptr to 0. Set relocation size in object_headers.
7996 (fill_section): Always set s_vaddr here, removing
7997 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7998 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7999 Set STYP_INFO for .comment.
8000 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
8001 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

8003 H_{SET,GET}_* macros.
8004 (do_linenos_for): Set lineno size in object_headers.
8005 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8006 set s_vaddr here. If string_byte_count remains 4, set it back to
8007 0, and only write strings out if there are some. Call
8008 fill_section before do_relocs_for and do_linenos_for.
8009 (obj_coff_section): Handle optional quoted second argument giving
8010 section characteristics.
8011 (obj_coff_bss): Added to handle .bss.
8012 (obj_coff_ident): Added to handle .ident (puts string in .comment
8014 (obj_coff_lcomm): Put common symbols in .bss, not .data.
8015 (fixup_mdeps): Change to segment. Call frag_wane after
8017 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8018 adjustment (already happened only for common symbols, but this is
8020 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
8021 * config/tc-i386.c (s_bss): Don't use if I386COFF.

8031 * app.c (app_push): Use memcpy, not bcopy.
8032 (do_scrub_next_char): For \", return " not '.
8033 (symbol_chars): Now const.
8035 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8036 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8038 * config/obj-coff.h: Don't use #elif.
8040 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8041 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8067 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8068 using ZERO_BASED_SEGMENTS.
8069 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8070 never set segment address for SEG_E2 (.bss) and don't write out
8071 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8072 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8073 definitions, and don't merge tags with non-tags. Check for .bf
8074 rather than just checking whether the second character is b and
8075 the third character is f.
8076 (obj_coff_val): gcc can generate values which we don't handle
8077 correctly; discard information for now, since it only affects the
8078 debugging information.
8079 (tag_find_or_name): Don't insert tags in the symbol table.
8080 (yank_symbols): Don't merge labels.
8081 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8085 used in AT&T i386 syntax.
8086 (fixup_segment): Take segment as argument. On the i386, adjust PC
8087 relative addends by the segment vaddr.
8088 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
8089 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

8226 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
8227 could be doing emulation.
8229 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8232 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8261 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8263 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8264 constant will not fit in an immediate field.
8265 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

8300 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8302 * Support for i386-sysv.
8303 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8327 * tc-m68k.c (get_num): make it work for all segments, not just the
8330 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
8332 * configure.in: recognize i386-*-bsd emulation.

8341 * tc-z8k.c: lots of bug fixes
8343 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8345 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8346 #elif, since it is not supported by old compilers.
8347 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8348 couple of expressions in tc-m68k.c.
8350 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8352 * read.c (cons): If NO_RELOC is defined, use it.
8354 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8356 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8358 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8359 local labels to start with a .) and set REGISTER_PREFIX to %.
8360 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8362 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
8364 * messages.c: Comment changes.
8366 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

8373 * listing.c (debugging_pseudo): Add stabs and stabn as things to
8376 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8378 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8379 sections starting from zero, rather than making them consecutive.
8380 This makes subsequent reloc calculations easier, esp if the object
8381 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8382 allocate lcomm in .data rather than in .bss. It seems that some
8383 tools can't cope with a non-zero sized bss before linkage.
8385 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8387 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8388 throughout. That enum no longer means what we thought it meant.
8390 * tc-m68k.c (md_assemble, md_parse_option): Handle new
8391 "-mno-688[58]1" options.
8393 * tc-m68k.c: Added CPU32 support.
8395 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

8401 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
8402 Change LIBDEPS dependence to LIBS.
8404 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
8406 * Makefile.in (install): if $(tooldir) exists, install as in
8409 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8411 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8412 .word is < -32768 or > 32767. The -J flag causes the error to be
8413 ignored. This is to catch over-sized switches generated by gcc on
8414 systems which don't support the broken .word hack.
8415 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8416 write.c (fixup_segment): check for signed .word overflow if
8417 WARN_SIGNED_OVERFLOW_WORD.
8419 * write.c (fixup_segment): fixed missing parens in expression
8420 checking for byte or word overflow.
8422 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
8423 obj-coffbfd.c (fixup_segment): check for signed .word overflow if

8431 Support for i386 coff
8432 * obj-coffbfd.h : added stuff
8433 * tc-i386.c (tc_coff_fix2rtype): new function
8434 * tc-i386.h : new coff defines
8436 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8438 * input-scrub.c (input_scrub_push): call input_file_begin, not

8533 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8534 written with indirection on the last two operands, which can be
8535 either data or address registers. Added a new operand type 'r'
8536 which accepts either register type. Added '(' to notend stuff in
8537 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8880 really strange things with things like fbge,a
8882 * as.h: include bfd.h if using many sections
8883 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so

8892 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8894 * app.c: MRI compatibility - allow single quote to start a string.

8896 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8897 * expr.c: Much rewriting, to accomodate MRI syntax for
8898 expressions. Also easier to read now.
8899 * listing.c: Put back defuns
8900 * read.c: modified to accept MRI syntax, put back listing pseudo
8901 ops so that an assembler built with NO_LISTING ignores list ops
8903 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8904 machine is a SPARC or a 29K.
8905 * config/obj-aout.c: added s_sect pseudo op
8906 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8907 fill in the timestamp.
8908 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8909 anymore, define all the relocs which the tc-<x> bit will use so we
8910 can translate from them to the coff types.
8911 * config/tc-a29k.c: reloc_type isn't ane enum any more
8912 * config/tc-m68k.c: Added NO_RELOC definition.

8927 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8929 * symbols.c (local_label_name): symbols now start with ^A.
8931 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8932 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8933 generate these sections. .align: will use NOP_OPCODE or 0
8934 for padding. This is just for being nice to the
8937 * expr.c (operand): changed to generate local label "\001L0"
8938 starting with a ^A so that it is recognized as a local label.
8940 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8942 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8943 i/o opcodes - inb, inw, outb and outw. string manipulation with
8944 att syntax - scmp, slod, smov, ssca, ssto.
8946 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8947 to just after .file .
8949 In obj_crawl_symbol_chain() where it tries to put the external
8950 symbols apart, with the condition:
8951 (!S_IS_DEFINED(symbolP) &&
8952 !S_IS_DEBUG(symbolP) &&
8953 !SF_GET_STATICS(symbolP))
8954 it was moving too many symbols out. So I switch it back to the
8956 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8958 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8959 so that we don't use the F_RELFLG which make the linker complain
8960 that somebody has stripped the relocation info.
8962 Also, the AIX ld program require that the relocation table
8963 is sorted by r_vaddr like the standard ATT assembler does.
8965 [he also changed the sizeof(struct ...)'s into the coff
8966 style FOOSZ macros. I'm not sure this is right, but I can't
8967 remember why. xoxorich.]

8971 * Makefile.in, configure.in, doc: use the doc. Build it, install
8974 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8976 * read.c: white space and comments only.
8978 * configure.in: use the new atof-ns32.c for ns32k.
8980 * write.c: comment change only.
8982 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8983 aren't yet integrated.
8985 * tc-i860.[hc]: blew off the dust. Something must still be done
8986 about conflicting relocation types.
8988 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8991 * tc-i960.c, tc-sparc.c: white space and comments only.
8993 * tc-a29k.h: delete duplicate macro definition.
8995 * new file atof-ns32k.c copied from hack's last unreleased gas.
8997 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8999 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9002 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9003 ChangeLog's prior to this are sketchy at best. I have logs.
9004 They just aren't ChangeLogs.
